How are current, voltage and resistance defined, and how does Ohm's law relate them?

Circuit concepts: charge, current, voltage (potential difference) and resistance, their units, and Ohm's law relating voltage, current and resistance.
An Eduqas GCSE Electronics answer on the core circuit concepts: charge and current, voltage as energy per coulomb, resistance, their units, and applying Ohm's law to find voltage, current or resistance in a circuit.

How do you measure voltage, current and resistance, and use instruments to test a circuit safely?

Measuring and testing circuits: connecting voltmeters, ammeters and multimeters, the difference between measuring across and through, and reading circuit and timing signals on an oscilloscope.
An Eduqas GCSE Electronics answer on measuring and testing circuits: connecting a voltmeter in parallel and an ammeter in series, using a multimeter for resistance and continuity, and reading voltage and timing from an oscilloscope.

How do you calculate the electrical power dissipated by a component and the energy it transfers?

Electrical power and energy: power as the rate of energy transfer, the equations relating power to voltage, current and resistance, and resistor power ratings.
An Eduqas GCSE Electronics answer on electrical power and energy: power as the rate of energy transfer, the three power equations, calculating energy transferred over time, and why resistor power ratings matter.

How do current, voltage and resistance behave in series and parallel circuits?

Series and parallel circuits: the rules for current and voltage in each, and combining resistors in series and in parallel.
An Eduqas GCSE Electronics answer on series and parallel circuits: how current and voltage divide in each, the rules that current is shared in parallel and voltage is shared in series, and combining resistors in series (add) and parallel (reciprocals).

How does the systems approach break an electronic product into input, process and output subsystems?

Electronic systems and subsystems: the systems approach with input, process and output blocks, block diagrams and signal flow, and analogue versus digital signals.
An Eduqas GCSE Electronics answer on the systems approach: representing an electronic product as input, process and output subsystems, drawing and reading block diagrams, tracing signal flow, and telling analogue and digital signals apart.
